Foundation Repair in Salinas, CA

A home’s foundation is crucial to its strength and stability. Regional soil types, ranging from sandy to silty clay loam, affect foundation stability due to drainage characteristics. Salinas, CA, receives approximately 15 inches of rainfall annually, leading to soil movement, erosion, and compromised foundation support. Signs of these issues may include foundation cracks, drywall cracks, floor and wall cracks, bowing walls, and uneven flooring. Bay Area Underpinning provides customized repair solutions, including advanced foundation pier systems, drilled concrete piers, pier and beam foundation repair, and PolyRenewal™ concrete lifting to repair and permanently reinforce foundation stability. 

Crawl Space Repair in Salinas, CA

Many Salinas, CA, homes feature moisture-prone crawl spaces susceptible to mold, musty odors, pests, and wood rot. Bay Area Underpinning offers comprehensive crawl space repair services to address these problems and improve indoor air quality. Our solutions include drainage systems, sump pumps, dehumidifiers, vapor barriers, insulation, support piers, and IntelliJack™ crawl space jacks to improve your home’s structural integrity and energy efficiency. Crawl space repair solves sagging floors, sticking doors and windows, and bouncy floors, and often lowers utility bills. Bay Area Underpinning’s crawl space repair services in Salinas, CA, safeguard the health of your home and family. 

Concrete Lifting in Salinas, CA

The soil and climate conditions in Salinas, CA, can lead to concrete settling and sinking over time. The moderate rainfall and sandy loam and clay soils lead to instability, erosion, and concrete deterioration affecting patios, exterior steps, driveways, sidewalks, and pool decks. These problems result in cracks, uneven surfaces, and potential trip hazards around your Salinas property. Bay Area Underpinning offers PolyRenewal™ polyurethane foam injections as a minimally invasive solution to lift and stabilize concrete surfaces. These durable foam injections are waterproof, environmentally friendly, and provide a quick 15-minute cure time, allowing for same-day use of the treated areas. Our professional concrete lifting services in Salinas, CA, restore the safety and curb appeal of your property. 


Properly repaired foundations can restore or even enhance the value of a home, especially in a competitive market like the Bay Area Underpinning.

Common methods include installing foundation piers and adding or adjusting support beams and screw jacks.

Concrete driveways sink, crack, and sustain other damage due to erosion beneath the slabs caused by expansive soil, soil instability, water intrusion from cracks, and growing tree roots. Heavy vehicles parked in the same place for extended periods can also cause driveways to sink. Contact Bay Area Underpinning for a free inspection to determine the source of the problem and the best solution.

It’s advisable to have a professional assess and fix any floor cracks promptly. The sooner you identify and address floor cracks, the easier and more cost-effective the solution will be.

Some of the most common issues and challenges associated with crawl space foundations are:

  • Moisture – Unless you live in a highly arid region, your crawl space will be prone to moisture-related problems. Excess moisture in a crawl space can lead to mold growth, wood rot, and structural damage.
  • Pests – Damp, dark crawl spaces also provide an ideal habitat for rodents and termites.
  • Poor Insulation – Since the crawl space isn’t livable, many homeowners may overlook proper insulation, leading to energy loss and higher utility bills.
  • Structural Damage – Poor foundation design, inadequate support, and soil movement can cause structural damage to a crawl space foundation over time, leading to cracks, uneven settlement, and other issues.
  • Poor Indoor Air Quality – A damp, moldy crawl space can lead to poor indoor air quality, including unpleasant odors, allergens, and other contaminants that can affect the health of the home’s occupants.
